Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various liquid containers such as electric pots, and more specifically, rises along one side of the body from the connection with the bottom of the body, and the outside of the body at the shoulder of the body. The present invention relates to a liquid container provided with a spout passage leading to a downward discharge port, and the rising portion of the spout passage serving as a transparent liquid amount display portion.

[0002]

2. Description of the Related Art Conventionally, the pouring path of a liquid container of this type is located on a vertical plane passing through the center of the container so that the liquid quantity display portion and the discharge port are aligned at the same position around the side circumference of the container. It is formed by being bent (for example, Japanese Utility Model Laid-Open No. 62-202227). The discharge port is located on the outer surface of the outer case of the body as it is or with a pipe cover, and the liquid volume indicator is located inside the outer case and is seen through from the outside through a display window opened in the outer case. It has become so.

[0003]

However, in the above-described conventional structure, the position where the display window is to be provided overlaps the position of the discharge port on the front side of the body where the discharge port is located.
For this reason, the display window can be provided only within a range where it is not obstructed by the ejection port. Especially as recently, the injection port or the injection port of the injection guide tube provided subsequently to it is at a relatively low position because it is said that it facilitates the injection from the container body that has been left stationary. If it is designed so that the range in which the display window is provided is further narrowed.

Therefore, it is conceivable to provide the liquid amount display section around the side circumference of the container laterally from the position of the front surface having the discharge port, that is, in the lateral direction of the container.

However, in this case, the actual exploitation of Sho 58-14829
As disclosed in Japanese Patent Publication, in the case where the pouring passage is provided with a liquid amount display section which maintains the same liquid level as this pouring passage, the pouring passage and the safety at the time of falling are secured and the pouring of the internal solution is performed. In order to accommodate a sufficient water shutoff valve at the time of fall between the inner container of the body and the outer case, the body becomes large in size so as not to impair the smoothness of the body.

Further, a display window formed on the outer case of the container to allow the liquid volume display portion to be seen is provided on the front panel integrally formed with the spout cover as described in the above publication. Then, the front panel is inevitably widened laterally by the amount of the liquid volume display section swung from the discharge port in the circumferential direction of the body, and the front panel becomes large.

In view of this, the present invention improves the liquid quantity display form by the spout passage together with the installation structure of the spout passage and the water stop valve at the time of falling, so that the above-mentioned conventional problems can be solved more advantageously. The challenge is to provide.

[0008]

In order to achieve the above-mentioned object, the present invention rises along one side of the inner container from the connecting portion of the container with the bottom of the inner container, and the container is held at the shoulder of the container. In a liquid container that has a spout passage leading to a downward discharge port facing the outside of the body, and the rising portion of this spout channel is a transparent liquid amount display unit, the liquid amount display unit is shaken in the lateral direction of the body from the discharge port position. Is connected to the discharge port as a closed position, and the liquid amount display unit is located inside the liquid amount display window that is also opened in the outer case of the body from the position of the discharge port. A water stop valve at the time of fall is installed between the discharge port and the discharge port, and this water stop valve at the time of fall is located inside the cover that covers the spout passage leading to the discharge port on the outer surface of the body. Make the outer diameter of the chamber larger than the outer diameter of the spout, and keep the distance between the inner container and the outer case It is characterized in that it has less than the outer diameter of the valve chamber.

[0009]

According to the above-mentioned structure of the present invention, the liquid amount display portion is laterally moved from the position of the discharge port for displaying the liquid amount by the liquid amount display window which is swung in the circumferential direction of the body from the position of the discharge port. Therefore, the liquid amount display portion of the spout passage itself can directly perform the liquid amount display window provided on the outer case without providing a special liquid passage other than the spout passage.

In particular, the outer diameter of the valve chamber of the water shutoff valve at the time of falling of the pouring path is made larger than the outer diameter of the pouring path, so that a sufficiently large valve for exhibiting the water stopping function at the time of falling. It is possible to ensure a sufficient passage cross-sectional area for accommodating the liquid and to discharge the internal solution smoothly, and the valve chamber is located inside the cover that covers the outlet passage leading to the outlet on the outer surface of the body. Therefore, the increase in diameter does not affect the body, and the distance between the inner container of the body and the outer case is smaller than the outer diameter of the valve chamber,
Regardless of the outer diameter of the valve chamber, it is possible to reduce the diameter of the outer case until the pouring path is inserted between the outer case and the inner container, and to downsize the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention shown in FIGS. 1 to 4 will be described. An inner container 2 having a heater 6 at the bottom is housed in an outer case 1 to form an electric pot body 3. Is forming. The outer case 1 and the inner container 2 are integrated at the upper end by the shoulder member 4, and at the lower end by a connecting fitting (not shown) and the bottom member 5. An outer lid 7 is provided on the upper end of the body 3. The outer lid 7 is detachably supported by a shaft 9 on a bearing 8 provided at the rear portion of the shoulder member 4, and pivots about the shaft 9 to open and close the body 3. Inside the outer lid 7, there are provided a bellows pump 11 which is pressed by an upper surface pressing plate 10 thereof, and a valve 12 which is arranged in the center thereof and is composed of a valve rod portion 12a and a valve packing 12b.

The air pressurized by the pressing operation of the bellows pump 11 is passed through a through hole 13 that connects the inside of the valve rod portion 12a and the inside of the bellows pump 11 through an air supply passage 14 to an inner lid 15.
Is sent into the inner container 2 through the opening 15a to pressurize the content liquid. The air supply passage 14 has an inner lid 15 and a bellows pump lower plate 16
A part of the passage space 17 formed between and is used.
The passage space 17 is formed by fixing a space between the bellows pump lower plate 16 and the inner lid 15 by screwing a spacer projection 16a integrally formed on the bellows pump lower plate 16.

In addition, the inner lid 15 has a mouth portion 2 of the inner container 2 on the outer peripheral portion.
The inner container 2 having the seal packing 18 closely attached to a is closed.

In the passage space 17, the bellows pump 11
At the time of the operation, the protruding portion of the valve packing 12b comes into close contact with the peripheral portion of the opening 15a of the inner lid 15 and shuts off the space between the outside of the outer lid 7 and the check valve 12c is added from the opened discharge port 12d. The compressed air can be reliably sent into the inner container 2 without leaking to the outside.

When the bellows pump 11 is not operated, the passage space 17 is also used as a steam release passage 20 for letting out the steam generated when the heater 6 keeps warm or boils to the outside of the outer lid 7. ing. As a result, when the content liquid is not poured, the vapor is discharged from the opening 15a of the inner lid 15 through the passage 121 at the rear of the bellows pump 11 to the outside through the opening 7a on the outer surface of the outer lid 7. Therefore, it is possible to avoid abnormal pressure increase in the inner container 2 due to the vapor pressure.

A pouring path 21 for guiding the pressurized content liquid to the upper outside of the container 3 is provided with its base end connected to the bottom of the inner container 2 (FIGS. 1 and 3). This pouring path 21 communicates with the inner container 2 and the bottom thereof, and rises along the side circumference of the inner container 2 so that the upper end is a shoulder member 4 part of the container 3 and is a downward discharge port 22 for the content liquid outside the container. It is connected and is always open to the atmosphere, and the content liquid in the inner container 2 always spontaneously flows in and maintains the same level as in the inner container 2. The rising portion of the pouring path 21 which keeps the same level as in the inner container 2 serves as an external liquid amount display portion 21a made of a transparent tube.

A liquid amount display window 23 is provided in the outer case 1 so that the level of the content liquid displayed on the liquid amount display portion 21a can be seen through from outside the body 3.

The discharge port 22 for the content liquid is a unit 26 with the valve chamber 25 of the water shutoff valve 24 at the time of fall, and is located in the upper portion of the pipe cover 4a integrally formed on the front portion of the shoulder member 4 and the shoulder member 4 is formed. Or, the pipe cover 4a is partially retained by screws or the like, or is stably held in the body 3 by fitting with a liquid injection pipe 27 that is detachably attached to the bottom of the pipe cover 4a. . The liquid injection pipe 27 receives and discharges the discharge port 22 which is communicated with the outside air outside the body 3 with a sufficient gap so as not to impair the communication state with the outside air. After the internal solution discharged from the outlet 22 is once released to the outside air and weakened in power, gently guides the internal solution downward so that it can be injected without problems such as spouting due to splash or splashing around. ing.

The liquid amount display portion 21a of the discharge passage 21 with respect to the discharge port 22 is swung laterally as viewed from the front of the body 3 where the pipe cover 4a is located, that is, in the lateral direction of the body 3. It is designed to stand up in a standing position. As a result, the liquid volume display window 23 corresponding to the liquid volume display portion 21a is similarly swung in the position immediately next to the position of the pipe cover 4a containing the discharge port 22, that is, in the side circumferential direction of the body 3. The liquid amount display portion 21a can be provided at a position immediately inside the position, and can be provided in a required height range using the entire length of the body 3 without obstructing the discharge port 22 and the pipe cover 4a. .

Therefore, the liquid amount can be displayed by covering the necessary fluctuation range of the actual liquid level in the inner container 2.

The upper end of the liquid amount display portion 21a which is swaying laterally from the discharge port 22 of the spout passage 21 is connected by a resin pipe elbow 29 to a substantially horizontal joint pipe 28 connected to the horizontal connection port 26a of the unit 26. It communicates with the discharge port 22.
Further, the lower end of the liquid amount display portion 21a is connected to the inner container 2 by connecting a resin elbow 30 attached to itself and a resin elbow 32 attached to a connecting pipe 31 protruding from the bottom of the inner container 2 with a joint pipe 33. By way of communication, the opening of the discharge port 22 is located at a height equal to or higher than the upper end of the joint pipe 28.

The liquid volume display window 23 is provided with a slit 1b at the bottom of a vertically elongated recess 1a formed in the outer case 1 and a sealing piece 1c made of a transparent resin film.

In addition, the water stop valve 24 at the time of falling is located in the pipe cover 4a which covers the discharge port 22 with the outer surface of the body 3 at a portion communicating with the discharge port 22 above the liquid amount display portion 21a of the spout passage 21. The outer diameter of the valve chamber 25 of the water shutoff valve 24 at the time of falling is made larger than the outer diameter of the spout passage 21, and the distance between the inner container 2 and the outer case 1 is made smaller than the outer diameter of the valve chamber 25. There is.

As a result, the water shutoff valve 2 when the spout 21 falls
Since the outer diameter of the valve chamber 25 of No. 4 is larger than the outer diameter of the spout passage 21, a sufficiently large water shutoff valve 24 at the time of fall is housed for exhibiting a water shutoff function at the time of fall. It is possible to ensure a sufficient passage cross-sectional area for the inner solution to be smoothly discharged, and the valve chamber 25 is provided on the outer surface of the body 3 to form the discharge port 22.
Since it is located in the pipe cover 4a that covers the spout passage 21 leading to the valve body 25, the increase in diameter does not affect the body 3, and the distance between the inner container 2 of the body 3 and the outer case 1 is set to the valve chamber 25. The outer case 1 can be made smaller than the outer diameter of the valve chamber 25 so that the spout passage 21 can be inserted between the outer case 1 and the inner container 2 regardless of the outer diameter of the valve chamber 25, and the body 3 can be downsized. .

The liquid amount display portion 21a is provided with a substantially horizontal joint pipe 28 provided between the upper end of the liquid amount display portion 21a and the position of the discharge port 22.
Since it is connected to the discharge port 22 via
The position of the pipe cover 4a is kept from the position of the discharge port 22 to the side circumferential direction of the body 3 while keeping a at a sufficient height so as to be sufficiently swung in the side circumferential direction of the body 3 from the position of the discharge port 22. It is possible to position it right inside the liquid volume display window at the position where the necessary amount is shaken.

Due to such a structure, the upper end of the liquid amount display portion 21a is connected to the unit 26 in a state of being swayed to the unit 26, so that it is difficult to stabilize and easily wobbles. This causes the appearance of the liquid from the liquid volume display window 23, impairs the commercial value, and causes rattling and liquid leakage at the connecting portions of the respective parts. Therefore, in order to prevent this, the connecting tube 3 facing upwards to the resin elbow 29.
4 is integrally formed, a downward connecting projection 35 is separately formed at a position laterally swung from the pipe cover 4a portion of the shoulder member 4, and the downward connecting projection 35 is fitted to the connecting cylinder 34 to form an upper end of the liquid amount display portion 21a. The part is connected to the shoulder member 4 so as to be firmly held on the container body 3 side (FIG. 4). If this is sufficient, it is possible to dispense with the special stabilizing, holding and fixing means of the unit 26.

The lower portion of the liquid amount display portion 21a is connected to the connecting pipe 31 firmly projecting from the inner container 2 so that it is difficult to sway, but in the present embodiment, for the sake of safety, the resin elbow 30 and the connecting pipe 3 are connected.
6 is integrally formed, and the upward connecting projection 37 integrally formed on the bottom member 5 is fitted thereto, and similarly to the above case, the lower portion of the liquid quantity display portion 21a is connected to the bottom member 5 and firmly fixed to the body 3 side. Hold on. However, this can be done as needed.

FIG. 5 shows a second embodiment of the present invention. In order to connect the upper end of the liquid amount display portion 21a to the shoulder member 4, a connecting projection 41 integrally formed on the resin elbow 29 and the shoulder member 4 are provided. The connecting cylinder 42 formed in the above is fitted together, and there is no difference in operational effect from the case of the first embodiment. As a unique structure of the present embodiment, the connecting pipe 28 is maintained in a state of having a downward inclination toward the liquid amount display portion 21a by the holding force of the connection. As a result, the discharge port 22
In addition, since the liquid amount display portion 21a which is swayed to the side is connected, the liquid pool in the horizontally extending connecting pipe portion 28 can be eliminated. The present invention is not limited to the above embodiments, but can be implemented in various modes. For example, the connecting portion and the connecting structure for holding the liquid volume display portion 21a on the body 3 side can be variously designed.

FIGS. 6 and 7 show a third embodiment of the present invention, in which the liquid quantity display portion of the spout passage 21 of the first embodiment is provided so as to be laterally swung with respect to the unit 26. Unit 2
By utilizing that there is nothing under 6, a liquid level detection unit 51 for securing a safe liquid level is provided as shown in FIG. The liquid level detection unit 51 has a vertical pipe 52 provided so that the upper and lower ends thereof communicate with the inner container 2, and a full water level detection float 53 and a minimum water level detection float 54 are housed in the vertical pipe 52. .

The float 53 detects the upper limit water level, that is, the full water level, which can prevent the content liquid from naturally flowing out through the pouring path 21 due to the shaking of the liquid surface when the content liquid boils. To detect this, a reed switch 56 that detects the magnet 55 in the float 53 at a position corresponding to the full water level is provided at a predetermined position.

The float 54 is for detecting the lowest water level at which the content liquid becomes small and there is a danger of cooking in the air. To detect this, the reed switch for detecting the magnet 57 in the float 54 at the position corresponding to the lowest water level. 58 is provided at a predetermined position.

These reed switches 56 and 58 are shown in FIG.
It is connected to the heater control circuit 61 shown in FIG. Circuit 61
Has a warming heater 6a and a boiling water heater 6b, and the relay 64 is turned on depending on whether the boiling water thermostat 62 is turned on or the re-boiling switch 63 is artificially turned on when the content liquid is lower than the warming temperature and the minimum temperature. The contact point 64-1 is turned on with self-holding, the contact point 64-2 is kept on, and the heaters 6a and 6b are energized to enter the water heating mode. When the content liquid boils in the boiling water mode, the boiling sensor is turned off, the relay 64 is turned off, and the contact 64-2 is turned off to switch to the heat retention mode in which only the heat retention heater 6a is energized.

In such an operating state, both reed switches 5
This is possible because both of the magnets 6 and 58 are in the ON state without detecting the magnets 55 and 57.
When any of the magnets 58 detects the magnets 55 and 57 and is turned on, that is, when it detects the full water level or the minimum water level, the heaters 6a and 6b are de-energized to ensure safety.
At this time, the water level display lamp 66 is turned on to visually indicate to the outside that the water level is abnormal.

[0034]

According to the present invention, in order to perform an advantageous liquid amount display by the liquid amount display window which is swung in the lateral direction of the body from the position of the discharge port, the liquid amount display section can be changed from the position of the discharge port. Since it is shaken laterally, the liquid amount display section of the spout passage itself can directly perform the liquid amount display window provided on the outer case without providing a special liquid passage other than the spout passage.

Particularly, since the outer diameter of the valve chamber of the water shutoff valve at the time of falling of the pouring path is made larger than the outer diameter of the pouring path, a sufficiently large valve for exhibiting the water stopping function at the time of falling. It is possible to ensure a sufficient passage cross-sectional area for accommodating the liquid and to discharge the internal solution smoothly, and the valve chamber is located inside the cover that covers the outlet passage leading to the outlet on the outer surface of the body. Therefore, the increase in diameter does not affect the body, and the distance between the inner container of the body and the outer case is smaller than the outer diameter of the valve chamber,
Regardless of the outer diameter of the valve chamber, it is possible to reduce the diameter of the outer case until the pouring path is inserted between the outer case and the inner container, and to downsize the body.
